Planned maintenance · built aboard

The yacht management system that lives on your boat.

Planned maintenance, statutory record books, inventory, crew and compliance for 30–70 m yachts — self-hosted on the vessel, working mid-Atlantic, with an AI engineer on watch.

Why crews choose it

Three things no cloud PMS can offer.

I

Your data stays aboard

The whole system runs on a small PC on the vessel. No cloud account, no third-party servers, no subscription that bricks your history. Owner's privacy by architecture — and it works fully offline, mid-ocean, updating only when you choose.

II

An AI engineer on watch

Ask it anything about your boat. It reads your live data and your actual manuals, remembers the vessel's quirks, drafts requisitions and defect reports for your confirmation, and emails the Captain a morning brief. Bring your own API key — you control the cost.

III

Built on watch, not in an office

Designed by a serving yacht engineer around real routines: hour-based PMS, per-cylinder exhaust-temp trending, watch handovers, tank soundings that drive the dashboard, an MEPC-format Oil Record Book. It matches how an engine room actually works.


The assistant

Ask your boat.

Answers come from live vessel data and your own documents — with sources shown, permissions respected per crew member, and crew privacy redacted by default.

What's overdue and what parts do we need for it?
The 250 h service on the starboard generator is due in 14 running hours. Its parts list calls for 1× oil filter (2 in stock) and 2× anodes (17 in stock) — no shortfall. Want me to raise the work order?Based on: Maintenance schedule · Inventory
What does the main engine manual say about lube-oil pressure?
The engine manual (§8.2.3) specifies the lube-oil pressure and temperature limits, filter grade and pre-lubrication requirements before starting…Based on: Document — Main Engines Operation Manual
Anything I should know this morning?
Morning brief: 1 overdue task (Gen 2 impeller), 2 certificates entering renewal, fresh water at 64% and falling faster than usual, and the Chief Stew logged a defect on the master-cabin AC overnight.Daily brief · emailed to the Captain at 07:00
  • Your key, your costs. Bring your own Anthropic API key (≈€10–30/month in practice). No key configured — nothing ever leaves the boat.
  • Reads your manuals. Upload the PDFs you already have; the assistant quotes them with the section number.
  • Proposes, never acts alone. It drafts the work order or requisition; a human always presses Confirm.
  • Remembers the vessel. Corrections and quirks are stored as vessel memory every future answer respects.

One system, whole vessel

Every department. Each crew member sees exactly their part of the ship.

Inspection-ready

When the surveyor comes aboard, you print.

Keelson keeps the statutory records the way the conventions describe them — filled in as part of the daily routine, not reconstructed the night before.

Oil Record BookMARPOL Annex I in the MEPC.312(74) structure — guided entries, three-step signing (officer → chief → master), strike-through corrections, audit trail, official book print.
Ballast Water Record BookBWM Convention format with tank identities and capacities taken from the vessel's own particulars.
ECA fuel changeoversMARPOL Annex VI log — entering and leaving control areas, tanks and sulphur content confirmed.
Engine & deck log booksWatch-based, signed and countersigned, void-with-reason instead of delete. Immutable by design.
MLC rest hoursCrew record their day; the rules are checked automatically and violations flagged before an inspector finds them.
ISM loopIncidents → root cause → corrective actions → verification. Inspections and audits from reusable templates. Certificates with renewal alerts.

Electronic record books require flag-State approval per vessel. Until yours is approved, Keelson works as the working log and transfers to the approved paper book via a certified true-copy print — we say that plainly rather than oversell it.


For the owner

One calm page for the person the boat belongs to.

An owner's login sees a single private portal — nothing to learn, nothing to click through.

  • Condition at a glance. Maintenance health, certificate status, open works — in plain terms.
  • Money, honestly. Budget against actual spend, with the variance visible.
  • Where she is. Position, itinerary and next port from the bridge's own records.
  • The monthly report, already written. A printed Owner's Report that matches what the crew actually did.

Honest answers

The questions a good captain asks.

What happens to us if you stop developing it?

Nothing bad. Keelson is self-hosted — it doesn't phone home and can't be switched off remotely. Your install, your database and your documents remain fully functional forever. Source-code escrow is available for fleet clients.

Does the AI send our data to the cloud?

Only when a crew member asks the assistant a question — and only the minimum needed to answer, sent directly to the AI provider using your own key. No key configured means nothing ever leaves the boat. Crew personal data is redacted from answers unless the user is the purser or captain.

Is the electronic Oil Record Book legally accepted?

It follows the MEPC.312(74) structure with three-step signing, strike-through corrections and an audit trail — but electronic record books need your flag State's approval per vessel. Until then, use it as the working log and transfer to the approved paper book via the certified true-copy print.

What do we need on board?

A small dedicated Windows PC on the ship's network. Crew use Keelson from any phone, tablet or laptop over the ship's Wi-Fi — nothing to install on their devices.

Can we import our existing records?

Yes — equipment registers, inventories and maintenance history are part of the setup service. Our own first vessel came in with eleven years of history from its previous system.

How do updates work at sea?

One click, when you have connectivity, at a moment you choose. The updater backs up the database first, applies the new version, and restarts — or stays put if the boat prefers not to change anything mid-season.


Adrian Vincent Amora, founder of Keelson
The person behind it

Built by the person who stands the watch.

Keelson wasn't designed in an office. It grew watch by watch in a working engine room, each feature added because the boat needed it that week.

Adrian Vincent Amora

Founder, Vincetech Labs · ETO / Engineer

Adrian first went to sea in 2006 — on deck, as a deckhand and chase-boat driver — and spent nearly a decade learning boats from the teak down before crossing to the engine room through dual deck-engineer roles on 30- and 71-metre yachts. Since 2014 he has kept the same 50-metre private motor yacht running as her ETO and engineer — today appointed her Chief Engineer by captain and management. Two decades at sea, over ten seasons in one engine room, every system aboard his responsibility.

He also happens to hold a degree in computer science. For ten of those years he logged maintenance in a PMS built far from the sea, by people who had never stood a watch — and quietly kept a list of everything it got wrong. Keelson is that list, answered: written in the crew mess and the control room of a working yacht, and tested every day on the very machinery it describes.

A Filipino engineer based in Italy — one of the seafaring people who quietly keep the world's fleets running — Adrian founded Vincetech Labs with a simple conviction: the software that runs a yacht should be built by someone the yacht has actually depended on.
